IMPROVEMENT IN BRAlD-GUIDES FOR SEWING-MACHINES.

Specification forming part of Letters Patent N0. 207,692, dated September3,1878; application filed July 20, 1878.

To all whom it may concern:

Be it known that I, EDDY T. THOMAS, of the city, county, and State of New York, have invented an Improvement in BraidGuides for Sewing-Machines, of which the following description,in connection with the drawing forming part thereof, is a specification.

This invention relates to improvements in that class of braiding-guides for sewing-machines in which is used a laterally-extended grooved arm for leading the braid to a needlehole of round or ordinary form; and the invention consists in a throat-plate provided with a V-shaped needle hole or passage, the small end of the said passage pointing in the direction toward which the material being braided is being moved.

The needle-hole, shaped as described, adapts it to receive and direct in a straight line braids of different widths, retaining each width so that its center is maintained centrally with relation to the center of the needle-hole for the passage of the needle.

Figure 1 represents, in plan view, abraidin gguide and throat-plate constructed in accordance with my invention, the braid being in place. Fig. 2 is a top view of the same, the braid being removed and the guiding-arm broken off; Fig. 3, a section on the line w at, Fig. 1-; and Fig. 4, a longitudinal section.

The throat-plate a is adapted to be held in place upon the sewing-machine by' a screw in the opening I), and is provided with afeedingslot, 0, and with a needle hole or passage, 01, made V-shaped, as shown clearly in Fig. 2, to guide the braid to be stitched upon a fabric.

The small end, 2, of this opening or passage d points in the direction of the forward move ment of the feeding device, as denoted by the arrow.

The edges of the braid 6, bearing against the inclined sides of the passage d, cause the braid, whatever may be its width, to be so guided and directed that the center of the braid will occupy a position exactly at the center of the passage d, so that the needle, in its descent through the said passage, will penetrate the said braid at its center.

The guiding-arm j, connected with and pro jecting laterally from the throat-plate, and extending over the cloth-plate, (not shown,) is provided with a groove, g, through which and underneath the fabric is led the braid on its way to the passage'd. The braid, after issuing from the groove 9, is directed upward through the passage din contact with the cloth.

The slots h permit of the introduction into the groove 9 of a pointed instrument to lead the end of the braid along said groove to the passage d.

I claim- 1. The improved braiding-guide or throatplate, provided with a V shaped passage, (1, for the braid and the needle, the smaller contracted end of the V-shaped passage being made to point in the direction of the forward movement of the feed, to guide and centralize braids of different widths, substantially as described.

2. The throat-plate provided with the feedopening and the V-shaped braid and needlepassage d, combined with the connected and laterally-extended arm f, to operate substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDDY T. THOMAS.
